Capt. Michael Davanzo, commanding officer of the Coast Guard Cutter Polar Star, conducts an interview with KCBS radio from the cutter’s bridge while the cutter is in a Vallejo, Calif., dry dock facility undergoing depot-level maintenance prior to the cutter’s next patrol, April 16, 2018. The current polar icebreaking fleet provides the minimum capacity to meet the nation's most critical icebreaking needs but does not facilitate year-round access to the polar regions or self-rescue.
